Re: Shipping SSL certificates in the base system
Thanks to Bennie for starting off this discussion. My apologies for
derailing things with the tzdata allusion.
I think we're all aware of the nature of trust wrt these certs. So
quite why everyone is shouting "THESE CERTS MIGHT BECOME STALE OR
UNTRUSTED, SO IT IS FAR BETTER TO CONTINUE TO TRUST EVERYTHING" is a
bit beyond me.
Look, we all know the drawbacks of certs, trusting untrusted third
parties to bootstrap trust, the swamp that is revocation, expired
certs themselves, PKI, broken or exposed private keys, and many, many
But they are better than nothing. Deal.
